The gender-neutral idiomatic nickname for a member of "Men's Rights Club" (MRC), a Seattle-based online feminist collective. MRC is for feminists who have been marginalized by the patriarchy and/or have been negatively impacted by being perceived as female (presently or previously).

I was having a really hard time dealing with a misogynistic coworker, but I posted about the problem on MRC and got some really great advice from my fellow Bing Bongs!

A twisted "game" created by motorcyclists that congregate at a San Diego bike night gathering (in Mira Mesa). Played by attempting to make (mostly harmful) physical contact with another player's genitals.

Players usually stand around in a circle (or semi-circle) discussing random topics and randomly a player will try to "bing-bong" another by taking a strike at their genitals. The game attempts to make use of several diversions, such as riddles or jokes to distract players.

"Hey, what's the capital of Thailand?"
"Bangkok!" (strikes opponent)

"I wrote you a poem..."
"Roses are red,"
"Violets are blue,"
"BING-BONG!" (strikes opponent).
